Subject: [PATCH v1 6/8] gadgetfs: Fix fallout of wait to swait completion change

The completion code has been changed using swait (simple wait) instead
of the more complex wait implementation. ep_io() is using not using
the wait_for_completation_*() helper function we need to update this
function accordingly.
